I bought one last summer, as a try-out, having seen guys using harnesses in the Caucasus Mts. I've used conventional straps all my life, but no more.... Whatever you may think, there is no cut or pinch at all from the shock cord. They're discreet, easy to pack and after a couple of weeks, completely natural (to the point i realised i still was wearing my bins an hour after getting home!)
You can also move fast without the optics banging on your chest, cross ditches without having to support your bins, climb over gates and stiles with both hands free.
Very comfortable, very easy to wear and highly recommended.

I have been using a strap style binocular harness for a few years. It's been far better for my neck than using the supplied strap.

However, I have to say that in my brief experience using this product, it is far more comfortable and easier to adjust than the strap style. It also does not bounce around as much. I haven't experimented with the different styles of wearing it, but I'm looking forward to doing so particularly as I often carry a camera (DSLR + 400mm) with me when birding.

I bought the harness to use with a smaller pair of 8X32 binoculars, but I was pleasantly surprised to find that they worked equally well with my heavier 10x42 binoculars as well.

The only thing left to wonder is if the elastic will last the distance, but it is quite thick and heavy duty as described, so no reason to think it won't. Only time will tell.

I was already using a similar harness that used sturdy cord and metal fixtures. When on a birding trip recently, I noticed one of the participants using this product. I bought it only recently and have worn it only two days in the field thus far. But I can tell it is a winner. The harness is very comfortable and well engineered. I can tell it will last.

This is the best harness-style bino support I've found, much easier in use than the strap-style harnesses. The ability to quickly adjust length to suit the bulk of different clothing is convenient, but I find the long 'ponytail' of surplus shock cord when I'm wearing a T-shirt can get caught up in thick cover. Can't have it both ways I guess.
Side note from Rick- Watch You Tube video on how to shorten your harness. See it on RYO site

This is the best and most comfortable harness I've ever used.It's very easy to put on and adjust.

This harness is the best one I have tried! I love how the binos just glide right up the cord and I am not constantly fighting with the straps (like I was with my old harnesses)! The binos stayed secure to my chest and the small cord was way more comfortable than the thick straps of other harnesses and didn't put pressure on my neck. I would recommend this harness to other hunters any day!

I hunt a lot of squirrels , I like to keep it light weight in the woods , this bino harness is the most simple and most stream line there is , not expensive and does its job very well , very nice design .

Great stuff. Simple, utilitarian, effective, versatile and well made.

I’ve heard from several people recently about your straps and I love them. DO NOT use metal rings they will eat away the metal on the bins and Swarovski will not fix a user error like that.
Note: Sally as a user of Swarovski for 25 years I do recall when they used aluminum for the Lug post in the late 90's and I wore through them with rings. They fixed the problem with magnesium lugs. I since tried to abuse them to see if they ware out and I can't. However when in doubt we sell a dandy set a binocular straps made of rubber and strong as heck. Key factor with straps, they need to be very short or you add swing to your set up which is not desirable. Our straps are very very short. View them on our site.
Thank you
